int count =1;
Create a program that creates 3 threads
The program has a global variable: int counter =
Thread 1, performs addition in 3 steps order
• Add 5
thread_function() {}
1
main() {}
Add 1
• Add 2
Thread 2, performs subtraction in 2 steps order
• Minus 2
• Minus 4
Sample Output
Thread 3, performs multiplication in 2 steps order
Multiply 10
Multiply 5
adding
after adding, counter now = 6
after adding, counter now = 7
after adding, counter now = 9
Combine all the techniques in previous slides to create the
program and show the output
Your threads should run in the order of addition,
subtraction, multiplication
subtracting
after subtracting, counter now =
7
after subtracting, counter now
= 3
multiplying
after multiply, counter now =
30
after multiply, counter now = 150
Your end total should be 150
